Hello. I have a Ralink with RT2561/RT61 chip. In Kubuntu 15.04 my connection is very unstable using NetworkManager, but with Wicd my connection is stable. Could you try Wicd? The problem is that in Kubuntu 15.04 is not possible uninstall "network-manager" because it also uninstalled "plasma-desktop". To test you should do:
$ sudo apt-get install wicd wicd-gtk During installation it will ask you to add your user to the group "netdev". $ sudo pkill -9 NetworkManager Start wicd from "menu" > "internet". If it does not start, you do: $ sudo rm /var/run/wicd/wicd.pid and try again. You note that Wicd does not automatically detect the encryption mode for your network. You must choose the password type from propierties. Probabily if you use WEP you should choose Wep (Passphrase), or if it Wpa you choose WPA 1/2 (Hex [0-9/A-F]). Also note that wicd connects to internet but will not tell you that you're connected, you try from the browser to know you are connected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1442908 Title: Realtek RTL8723BE wireless card drops connection in Linux kernel 3.19.0-13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442908/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
